[Vi ETALLIC LATH.

SPEGIFIOATION forming part of Letters Patent N 0. 725,115, dated April 14, 1903.

Application filed June 28; 19Q2.

To aZZ whom it nuty concern;

Be it known that I, VALENTINE MOESLEIN,

a citizen of the United States, and a resident of the city of New York, borough of Manhattan,in the county and State of New York,have invented new and useful Improvements in Metallic Laths,of which the followingis a full, clear, and exact description.

The object of the invention is to provide a new and improved metallic lath which is si'm ple and durable in construction and arranged to securely hold the plaster in position.

The invention consists of certain parts and details and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a face View of the blank for forming the lath. Fig. 2 is a plan View of the lath; and Fig. 3 is a cross-section of the same on the line 3 3 of Fig. 2.

Theimproved lath is produced from a blank in the form of a piece of sheet metal A, pro vided with spaced rows of slots, each consisting of spaced and approximately parallel ends B B, connected with each other at diagonally-disposed terminals by the connecting portion, preferably formed of two parallel members B" B starting at angles from the diagonal endterminals and connected with each other by the oblique middle portion B, as plainly indicated in Fig. 1. Each of the slots thus produced in the sheet-metal blank forms a pair of tongues O O, bent outwardly and projecting from one face of the blank,

the tongues of each pair extending in opposite directions and forming an elongated opening D in the sheet metal, as plainly shown in Fig. 2. Now it will be seen that each tongue extends integrally from about one-half of the side wall of the opening D, one tongue being located at each end of the opening and the other adjacent to the other end of the opening. The tongues O and O are preferably curved back toward the face of the piece of sheet metal. The slots B B and openings D of successive rows break j oints,as plainly shown in Figs. 1 and 2, and a tongue of an opening Serial No. 118,603. (No mo leh in one row is bent toward the free side of the adjacent opening in the next row, so that the tongues are equally distributed over the sheet-m etal lath, and thus support the plaster uniformly. In making the sheet-metal lath suitable cutters and dies are used, and by the arrangement described the tongues do not interfere with each other when struck up by the dies.

The material between adjacent openings D in each row is formed with abead E, extending on the rear of the lath that is, on the face opposite the one having the tongues O O. The beads E greatly strengthen the lath.

The lath produced in the manner described is exceedingly strong and securely holds the plaster in position.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A blank for a sheet-metal lath, formed from a piece of sheet metal, having slots, each consisting of spaced ends and a connecting portion extending at angles from the ends at diagonally-disposed terminals, as set forth.

2. A blank for a sheet-metal lath, formed from a piece of sheet metal having rows of spaced slots, each consisting of spaced parallel ends, and a connecting portion extending from diagonally-disposed terminals of the ends, the connecting portion consisting of parallel members and an oblique middle portion, as set forth.

3. A sheet-metal lath having openings at intervals throughout the same, and tongues struck up from the material of the openings, the tongues of an opening extending from opposite sides in opposite directions, and each tongue extending from one side of the opening approximately at one-half of the length of the side, as set forth.

4:. A lath of sheet metal having at intervals through the same openings of oblong shape, and a pair of tongues formed of the sheet metal turned outward in forming an opening, the tongues extending from the long side of the opening and approximately one-half the length of the side, as set forth.

5. A lath of sheet metal having at intervals throughout the same openings of oblong shape, a pair of tongues formed of the sheet metal turned outward in forming an opening, the tongues extending from the long side of the opening and approximately one-half the length of the side, the width of each tongue corresponding to the width of the opening, and the tongues of a pair being curved out- I wardly inopposite directions, as set forth.

6. A metallic lath having rows of openings tongues extending up from diagonally-oppoe site sides of said openings and formed from the material of the openings, said tongues being straight and parallel longitudinally and curved in cross-section, and beads integral with the lath and extending between adja- I 5 cent openings as set forth.

In testimony whereof I have signed my name to this specification in the presence 0 two subscribing witnesses.

VALENTINE MOESLEIN.
